zp2ss
Zero-pole to state-space conversion.
Syntax
[A, B, C, D] = zp2ss(Z, P, K)
Inputs
- Z
- Zero locations.
- P
- Pole locations.
- K
- System gain factor.
Outputs
- A
- The state matrix (n x n), where n is the number of states.
- B
- The input matrix (n x p), where p is the number of inputs.
- C
- The output matrix (q x n), where q is the number of outputs.
- D
- The direct transmission matrix (q x p).
